What does the term 'the place where two seas met' represent in the sermon?

In the sermon, 'the place where two seas met' serves as a powerful metaphor for the cross, where God's absolute justice—and His demand for sin's punishment—met with His unfathomable grace. This duality shows how God can be just by punishing sin while also justifying the ungodly through Christ's sacrifice. The calamity of the shipwreck is likened to our hopeless state before recognizing our need for Christ, emphasizing that true salvation is found in Him alone. This reflects the foundational Reformed understanding of substitutionary atonement and the assurance of salvation for the elect.
